The extent and risk of knee injuries in children aged 9–14 with Generalised Joint Hypermobility and knee joint hypermobility - the CHAMPS-study Denmark

Table 4 Odds Ratio for knee injuries in children with GJH with/without knee hypermobility

	OR (95 % CI)	P value	OR (95 % CI) unadjusted values	P value
GJH, group 1a (n = 36)
All injuries	0.83 a (0.37 - 1.84)	0.649	0.93 (0.49-1.78)	0.840
Traumatic injuries	1.56 c (0.43 - 5.61)	0.495	1.59 (0.66-3.86)	0.297
Overuse injuries	0.69 b (0.29 - 1.65)	0.407	0.73 (0.37-1.45)	0.379
GJH and knee hypermobility, group 1b (n = 26)
All injuries	0.99 a (0.40 - 2.44)	0.981	1.24 (0.60-2.55)	0.553
Traumatic injuries	2.22 c (0.60 - 8.19)	0.231	2.34 (0.94-5.80)	0.066
Overuse injuries	0.75 b (0.27 - 2.06)	0.576	0.89 (0.42-1.92)	0.782

Values are Odds Ratios (OR) adjusted for sex, age, school type, sports participation and growth with 95 % confidence intervals. Logistic regression model. P value indicates main effect of GJH on knee injuries. GJH = Generalised Joint Hypermobility. Groups presented by children with GJH (group 1a) and children with GJH and simultaneous knee hypermobility (group 1b). Unadjusted values represent the association of injury types and GJH only
a = sex, age and sports participation significance, growth borderline significance
b = sex, age, growth and sports participation significance
c = sports participation significance, growth borderline significance
